JAY W. FARNOFF, OF BUFFALO, NEW YORK, ASSIGNOR OF ONE-THIRD TO JOHN H. OASLER AND ONE-THIRD TO ARTHUR H. RICE, OF BUF- FALO, NEW YORK.

GAS-BURNER.

To all whom it mld/y concern:

Be it known that I, JAY W. FARNOFF, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement vin Gas-Burners, of which the following is a specification.

Thisinvention relates more particularly to a gas-burner in which the mantle is supported in a pendent or inverted position.

The object of this invention is the production of a burner of'this character which is extremely simple in construction and neat in appearance and which produces a very powerful light.

In the accompanying drawings, Figure 1 is a vertical section of my improved gas-burner. Figs. 2 and 3 are horizontal sections thereof in lines 2 2 and 3 3, Fig. 1, respectively. Fig. 4 is a sectional elevation, on an enlarged scale, of the gas-valve. Fig. 5 is across-section thereof in line 5 5, Fig. 4:. Fig. 6 is a fragmentary sectional elevation showing a modification of the means for adjustably supporting the mantle from the main or mixing tube.

Similar letters of reference indicate corresponding parts throughout the several views.

A represents the vertical main or mixing' tube, which preferably tapers downwardly and is constructed of lavite, although the same may also be made of metal or any other suitable material. Upon the lower end of the mixing-tube the mantle B is supported in a pendent position and preferably by the following means: C represents a metal ring, to the lower end of which the upper or open end of the mantle is secured and which is provided on diametrically opposite sides with laterallyprojecting supporting-ears c, thatare formed out of the body of the ring by slitting the upper edge of the same vertically and then bending the parts between the slits downwardly, thereby forming the ears and also forming recesses c' in the upper edge of the body in line with said ears. p D represents a sleeve which carries the mantle and is capable of vertical adjustment on the mixing-tube. This adjustment is preferably effected by providing the sleeve with an internal thread and engaging -the same with an external thread on the lower end of the mixing-tube, as shown in Fig. 1. Projecting outwardly from opposite sides of the sleeve are two horizontal arms d, each of which has a depending lug d at its outer end.

Specification of Letters Patent. Application filed May 19,1905. Serial No. 261,130.

Patented Sept. 19, 1905.

E represents horizontal set-screws, which work in threaded openings in the'lugs d'. In assembling the parts the adjusting-sleeve is first screwed onto the mixing-tube. The supporting-ring ofthe mantle is next placed around the mixing-tu be so that its recesses receive the arms CZ of the sleeve and the ears thereof bear against the under side of said arms. Upon now tightening the set-screws so that they engage with the under side of said lugs adjacent to the supporting-ring the Ylatter is secured to the tube. The ears of the mantlesupporting ring preferably incline from their outer toward their inner ends, and the setscrews are so arranged that they bear against the inclined under sides of the ears, as shown in Fig. 1. By thus engaging the arms d with the recesses of the mantle-ring and the set- 'screws with the ears thereof this ring and its mantle are securely connected with the mixing-tube and the burner is permitted to be tilted at an angle without liability of displacing the mantle relativelyy to the mixing-tube.y

By screwing the supporting-sleeve up or down on the mixing-tube mantles of varying length may be adjusted so asto stand` centrally in the globe F, which surrounds the mantle.

While I prefer the construction-of mantle supporting and adjusting device shown in Figs. 1 and 3, the means for supporting the mantle in the globe may be varied. For instance, as shown in Fig. 6, the adjustingsleeve D' may be provided with a plurality of laterally-extending arms (Z2, having seats on their upper sides which are adapted to receivev IOO for holding the same in place, as shown in Fig. 1. The top of the globe-holder is of skeleton form, and the globe is provided at its bottom with a central opening and in its top around the holder with openings L to permit the air to circulate freely through the globe and prevent excessive heating thereof.-

' against each other; but their upper ends are receives a crank pin or Wrist r.

separated by an intervening space. rlhe preferred means of securing the deiiector and mixing-dome to the mixing-tube consists in providing the lower end of the defiector with a collarj', which surrounds the upper end of the mixing-tube and bears against the upper side ofl the globe-holder, and providing the lower end of the mixing-dome with an upturned and internally-screw-threaded collar t', which engages with an external thread on the upper end of the mixing-tube. Upon tightening the mixing-dome on the mixing-tube the collar of the deflector is clamped between the dome and the globe-holder, thereby holding these parts firmly on the mixing-tube. At its upper end the mixing-dome is provided with an outwardly-projecting annular iange K, which bears at its edge against the inner side of the defiector, at the upper end thereof'. Extending horizontally over the top of' the mixing-dome and its iange is a top plate L, having a central-opening and a plurality of segmental openings Z around the central opening which place the dome in communication with the atmosphere. The dome-flange and the top plate are securely united to the deflector by a head or seam m, formed on the upper edge of' the deflector and turning upwardly and inwardly over the outer edges of the superposed flange K and top plate L, as shown in Figs. 1 and 2. The case or body iT of' a gas-valve extends downwardly through the central opening of the top plate and is secured therein, preferably by providing said case and opening with cooperating external and internal screwthreads, respectively. The chamber of this case has the inlet at its upper end connected with a gas-supply pipe 0, while the outlet-nozzle at its lower end is provided with an internal valve-seat p. the valve-case is a vertically-movable and longitudinally-grooved valve-stem Q, having a valve q at its lower end which moves toward and from the seat 1J for opening or closing the outlet-nozzle. In its side the valve-stem is provided with a transverse groove q,which rlhe latter is arranged eccentrically on the inner end of a horizontal shaft or spindle R, which is journaled in a bearing in the adjacent part of the valve-case. Outside of the case the spindle is provided with a thumb piece or button i Within the chamber of against axial movement in its bearing by meansof a teat s, which is formed by punchmarking, indenting, or pressing the stock of the -valve-casing inwardly into an annular groove s' in the spindle, as shown in Fig. 5. Upon turning the spindle the position of the valve relatively to its seat may be varied as may be necessary to produce the proper mixture of' the same in the dome with the air entering through the openings Z. ln order to enable the volume of air to be also regulated, a rotatable shutter T is pivoted on the valvecase between a shoulder thereon and the upper side of' the top plate and provided with a plurality of wings z5, which cover the airopenings more or less, according as the shutter is turned. For convenience in manipulating. the air-shutter the same is provided with a finger piece or lip t', as shown in Figs. l and 2.

Within the upper part of the mixing-tube is a guard-tube U, which prevents the flame at the mantle of' the burner from iiashing backward and igniting the gas at the valve. This guard-tube tapers downwardly and fits tightly at its upper end in the upper end of' the mixing-tube, while its lower end is separated therefrom by an intervening annular space. For, convenience in assembling the guard-tube with the other parts of' the burner the upper end thereof is provided with an external annular flange u, which bears against the upper end of the mixing-tube, and thus serves as a stop for limiting the downward movement of the guard-tube in the mixingtube. If' the flame tends to flash back, the same passes around the outer side ofthe guardtube instead of upward through the center thereof, thereby preventing the iiame from reaching the gas-regulating valve.
